Phase 1/2 Study of Ensartinib and Durvalumab, in ALK-rearranged Non-small Cell Lung Cancer

Completed · Phase 1/Phase 2

Conditions studied: Non-small Cell Lung Cancer, Carcinoma, NSCLC

In brief

This was a Phase 1/2, open-label, multicenter, single-arm study of combination therapy with ensartinib, an anaplastic lymphoma kinase (ALK) inhibitor, and durvalumab, an anti-programmed cell death ligand 1 (PD-L1) antibody, in subjects with ALK-rearranged (ALK-positive) non-small cell lung cancer (NSCLC). Primary study objectives were to determine the recommended combination dose (RCD) and safety and tolerability of the combination. Further objectives were to evaluate the clinical efficacy and biologic activity of the combination.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologic confirmation of metastatic NSCLC. Subjects must have had confirmed ALK rearrangement as assessed by immunohistochemistry. Subjects may have had prior therapy with ALK inhibitors (other than ensartinib) or been ALK inhibitor naïve. ALK inhibitor naïve subjects were informed of the availability of approved ALK inhibitors.
• Measurable disease according to RECIST 1.1, defined as ≥ 1 lesion that could be accurately measured in ≥ 1 dimension (longest diameter to be recorded for non-lymph node lesions, shortest diameter to be recorded for lymph node lesions). Each lesion must have been ≥ 10 mm when measured by computed tomography, magnetic resonance imaging, or caliper measurement by clinical examination or ≥ 20 mm when measured by chest x-ray.
• Willing to provide a fresh pre-treatment biopsy; however, if subject was ALK inhibitor naïve, either archival or pre-treatment biopsy was acceptable.
• Asymptomatic subjects with surgically treated brain metastases must have been ≥ 14 days post surgery at the time of first dosing, while clinically stable with no requirement for steroids. Asymptomatic subjects with radiation-treated brain metastases may have entered the study immediately after completion of the radiation (and been off steroids, if applicable). Symptomatic subjects (those experiencing headache, seizure etc.), must have been relieved from all symptoms of their central nervous system disease, and must have completed radiation and been off steroids prior to first dosing (anti seizure medicine permitted).
• Laboratory parameters for vital functions should have been in the normal range. Laboratory abnormalities that were not clinically significant were generally permitted, except for the following laboratory parameters, which must have been within the ranges specified, regardless of clinical significance:
• Hemoglobin: ≥ 9 g/dL
• Neutrophil count: ≥ 1.5 x 10\^9/L
• Platelet count: ≥ 100,000/mm\^3
• Serum creatinine: ≤ 1.5 x institutional upper limit of normal (ULN), OR creatinine clearance: ≥ 50 mL/min (by Cockcroft-Gault formula)
• Serum total bilirubin: ≤ 1.5 × ULN (except for subjects with Gilbert's syndrome who were allowed after consultation with their physician)
• Aspartate aminotransferase (AST)/alanine aminotransferase (ALT): ≤ 2.5 x ULN
• Alkaline phosphatase: ≤ 2.5 x ULN
• Eastern Cooperative Oncology Group Performance Status ≤ 2.
• Age ≥ 18 years.
• Able and willing to provide valid written informed consent.
• Able and willing to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow-up.
• Body weight > 30 kg.

You may not qualify if…

• Treatment with an investigational agent within 4 weeks of starting treatment, and any prior drug-related toxicity (except alopecia) should have recovered to Grade 1 or less.
• Prior treatment with anti-PD-1, PD-L1 (including durvalumab), or cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), or ensartinib (X-396).
• Active, suspected or prior documented autoimmune disease (including but not restricted to inflammatory bowel disease, celiac disease, Wegner's granulomatosis, Hashimoto's thyroiditis, rheumatoid arthritis, systemic lupus, scleroderma and its variants, multiple sclerosis, myasthenia gravis). Vitiligo, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger were permitted.
• Subjects with clinically significant cardiovascular disease, including:
• New York Heart Association Class II or higher congestive heart failure.
• Myocardial infarction, unstable angina, cerebrovascular accident or transient ischemic attack within 6 months of start of study drug (Day -28).
• Clinically significant supraventricular or ventricular arrhythmia.
• QT interval corrected using Fridericia's formula (QTcF) ≥ 450 ms (male) or QTcF ≥ 470 ms (female).
• Clinically uncontrolled hypertension.
• History of pneumonitis or interstitial lung disease, or any unresolved immune-related adverse events following prior therapy.
• Major surgery within 4 weeks of starting treatment (or scheduled for surgery during the projected course of the study).
• Women of child bearing potential who were pregnant as evidenced by positive serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin) or nursing.
• Female subjects of childbearing potential who were sexually active with a non-sterilized male partner must have used at least one highly effective method of contraception (see table below) from the time of screening and must have agreed to continue using such precautions for 90 days after the final dose of investigational products. Non-sterilized male partners of a female subject must have used male condoms plus spermicide throughout this period. Cessation of birth control after this point should have been discussed with a responsible physician. Not engaging in sexual activity for the total duration of the trial and the drug washout period was an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method were not acceptable methods of birth control.
• Female subjects should have refrained from breastfeeding throughout the period described above.
• Females of childbearing potential were defined as those who were not surgically sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or post-menopausal.
• Females were considered post-menopausal if they had been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements applied:
• Females <50 years of age were considered post-menopausal if they had been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they had luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
• Females ≥50 years of age were considered post-menopausal if they had been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year prior to study entry, had chemotherapy-induced menopause with last menses >1 year prior to study entry, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
• Non-sterilized male subjects who were sexually active with a female partner of childbearing potential must have used male condoms plus spermicide from screening through 90 days after receipt of the final dose of investigational products. Male subjects were to refrain from sperm donation throughout this period. Female partners (of childbearing potential) of a male subject must have used a highly effective method of contraception (see table below) throughout this period. Cessation of birth control after this point was to be discussed with a responsible physician. Not engaging in sexual activity for the total duration of the trial and the drug washout period was an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method were not acceptable methods of birth control.
• A highly effective method of contraception was defined as one that resulted in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Note that some contraception methods were not considered highly effective (e.g. male or female condom with or without spermicide; female cap, diaphragm, or sponge with or without spermicide; non-copper containing intrauterine device; progestogen-only oral hormonal contraceptive pills where inhibition of ovulation was not the primary mode of action [excluding Cerazette/desogestrel which was considered highly effective]; and triphasic combined oral contraceptive pills).
• Subjects who were immunosuppressed, including those with known immunodeficiency.
• Active infection including tuberculosis (clinical evaluation that included clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice), hepatitis B (known positive hepatitis B virus surface antigen result), hepatitis C, or human immunodeficiency virus (positive 1/2 antibodies). Subjects with a past or resolved hepatitis B virus infection (defined as the presence of hepatitis B core antibody and absence of hepatitis B virus surface antigen) were eligible. Subjects positive for hepatitis C antibody were eligible only if polymerase chain reaction was negative for hepatitis C virus ribonucleic acid.
• History of severe allergic reactions to any unknown allergens or components of the study drugs.
• Other serious illnesses (e.g., serious infections requiring antibiotics, bleeding disorders).
• Mental impairment that may have compromised compliance with the requirements of the study.
